Fast Motion Estimation with Extended Block Sizes for High-definition Video Coding
نویسنده
چکیده
H.264/AVC video coding standard performs motion estimation using various motion partition sizes. It has been shown to improve the coding gain. However, video coding using blocks bigger than 16×16 pixels can provide a substantial coding gain compared to H.264/AVC, especially when applied to high definition video sequences. Even if coding efficiency is improved, the complexity of motion estimation using extended motion partition sizes is also increased. For high definition video coding, fast motion estimation using extended motion partition sizes has been proposed. In order to reduce the complexity, we propose a fast motion estimation method for extended block sizes. Experimental results show that the proposed algorithm reduces the complexity of motion estimation without any visible performance degradation.
